Spatial structures have the different dynamic characteristics from general rahmen structures. But, because most researches of vibration control were conducted for rahmen structures, the usable results of those researches are very limited for vibration control of spatial structures. This studies is conducted about the arch structures that the basic dynamic characteristics of spatial structures is inherent in, and the change of its seismic response is analyzed according to installation location of TMD(Tuned Mass Damper). The seismic response of arch structure is effectively reduced, when TMD is installed on a quarter of its arc length.
